Abstract

Data storage has become an important issue inwireless Sensor Networks (WSN) as a hugeamount of collected data needed to be archived forfuture reference. Storage nodes are introducedhere to store the data collected from the sensors intheir proximities. The storage nodes alleviate theheavy load of transmitting all data to a centralplace for archiving and reducing thecommunication cost induced by the networkquery. This paper proposes a new securitymechanism to store the data and the queryprocessing through the secure routing in WSN,and also addresses the storage node placement,aiming to minimize the total energy cost forgathering data to the storage nodes, replyingqueries and level of encryption for extend thesecurity for data communication. This paperexamines the secure routing protocol for queryprocessing and data transmission in it.
